A couple of Dark Tourism stories today: the "Toxic Tour" in Los Angeles is free and growing in popularity; and China works to end organ transplant tourism. Then I discuss a couple of Web 2.0 Travel Sites from Emily Chang's eHub site: DigiLondon.com and GeoBeats.com. And related to this, the giant travel review site, TripAdvisor.com is starting to experiment with user videos.
